Four farmers cooperatively take care of a 2 hectare farm that was awarded to them through the Agrarian Reform Program of the government. Initially, they have to clear the land of bushes and shrubs/ scrubs, make ridges, before finally planting cassava. How many days would they need to complete each tasks? How much power would be consumed in everyy activity (KVW-hr)? Assume that the farmers work 8 hours a day including rest periods.

Rest Period

Tr = 60(1-250/P)
whereas:
Tr = required rest period, min/hr of work
P = actual rate of energy in consumption in watts.
